Question

Square root of (x+deltaX)+ 2 - square root of (x-2)/ delta x

Answer 1

\[\sqrt{x+\Delta x}+2-\sqrt{\frac{x-2}{\Delta x}}\]??

Answer 2

no the (delta)x is over both sqaure roots only

Answer 3

maybe
\[\frac{\sqrt{x+\Delta x}+2-\sqrt{x-2}}{\Delta x}\]

Answer 4

yes but the +2 is also under the square root

Answer 5

\[\sqrt{(x+\Delta x)+2} - \sqrt{x+2} / \Delta x\]
